T0 aZZ whom 'it may concern:

Be it known 'that I, OLIVER A. Knysna, a citizen of the United States of America, und 'a resident of the city of Bartlesville, in the county of l/Veshington and State of Oklahome, have invented a new and useful iinprovenient in pumps for use in deep Wells in raising oil and other mineral iuids troni great depths to the surface; and I hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled 'in the art to make use -of the same, reference being had to the accompanying drawing, forming a part of this specification.

In the pumps now used in raising oil and other mineral fluids to .the surface from great depths, the fluid in the Working or punip-barrel passes through a 'valve in the sucker or piston directly into the shaft above the pump-harrel,A and the'sand and sediment in the iiuid passes through the valve and around the sides of the sucker,

' having a tendency to Wear out the valve-cups f tion is that by the use of thesand-protector attached to the piston, necessitating-and especially4 in case of oil v vells-the frequent pulling of the rods troni the Well for the purpose of replacing the wornout valvecups. k

One of the purposes of thisinvention is to so arrange the parts of the pump that, instead of passing directly through a valve in the piston into main shaft above the pumpbarrel, the iiuid passes from the pump-barrel through a side-pipe or tube and back into the main shaft above the.pump-bairel, thus preventing the sand and sediment in the iiuid from passing around the sides' of the piston and Wearing out thev valve-cups, thus saving their cost, the cost of pulling the rodsfroin the Well to replace the valve-cups, and the loss of time in extracting the fluid While the pump is being repaired.

In the pump described in this speciication, the downward stroke forces the fluid into the side-pipe or tube from the puinpbarrel, the piston pushing down upon the Weight of the fluid in the shaft above, through the open valve G, the weight of the rods being suiiicient to carry the piston down, and the Weight of the iiuid in the main shaft being neutralized hy its pressure both above and below the piston on the downward stroke.

described in this sp'ecicaticn the worlu'ng barrel and piston 1s protected from the sand;

and sedimentwhioh necessarily settles down `:When the pump is shut down for any cause.

The accompanying drawings represent e I Central vertical section ot' the saine, Figure 2 the upl representing the lower and Fig. per part of the pump; wherein:

A, represents the main shaft through which the fluid is drawn from the hottoin to the top ot the Well.

B, represents the holes in the pipe belowY the pump-barrel through which the fluid enters the pipe. i C, represents the valve, lopening upward, in the main shaft, in the bottoni of the pump-barrel, through which the rluid enters the pump-barrel on the upward strolre ci? the piston, and which prevents the backward flow of the uid.

D, represents a side-pipe or tube which opens into the pump-barrel, at E, any desired point above the valve C, and below the lowest point oi the downward stroke of 4the piston in the punip-harrel, and at F, any convenient point in main shaft above pump-barrel.

G, represents the valve opening upward. at a convenient point in the side-pipe or tube D, which prevents the backward flow of the duid.

H, represents the piston-rod, to the end of which is attached the piston, which ei:- tends from the piston in the punipharrel, to the top of the well Where the power is applied in the usual manner.

l, I', J, l, L, lli and N represent the several parts of the piston, attached to the piston-rod. There is no valve or opening in the piston, and the parts are so arranged with two reversed series of valve-cups as to clean the punip-hsrrel on coth the upward and downward strokes of the piston to prevent the fluid and sand or sediment from passing through or around the saine.

More particularlyml, represents the upper series of cups, composed of several valve cups, edusted on the piston in the usual manner, With the usual Washers M between,

ice

faced downward to prevent the fluid in the pump-barrel from passing around the piston into the upper surface of the top valve-cup,

thus holding the parts of the piston firmly 1n place between it and the lock-nuts L. l

The sand-protector is compesed of two members: O, represents the lower member 4of the sand-protector, through which the piston-rod passes, composed of a pipeattached to-a base Q, with a beveled lower surface resting on a beveled seat in thetop of the workin barrel which is a convenient point above t e piston and below the upper opening of the side-pipe into the main pipe at "F, said member extending on the piston-rod for a convenient distance above the pumpbarrel. P, represents the upper member of the sand-protector, being an inverted pipe around the piston-rod, closed at .the top, open at the bottom, securely attached to the piston-rod at the top andl telescoping over the lower member of the sand-protector O.

Q, represents the base of the lower member O.- It has abeveled lower surface and rests on a beveled seat, T, in the top of the pumpbarrel 'abdve the piston and below the 'pening, F.

R, represents the horizontal groove around the outer surface of the base Q.

S, represents one o r more springs attached in a collar, U, around-the main pipe, which fit into the groove R, and hold the member O in its place on the .beveled seat T; but which flatten on the application of suflicient power and permit the pulling of the piston and sand-protector from the well. l

T, represents a beveled seat in the top of the pump-barrel on which the member O rests. i

U, represents the collar around the main pipe, in which the springs S are set.v

T he operation of Vthe pump 4is as follows: 'Upon the upward stroke of the piston, the weight of the fluid above closes the valve G, the valve C opens, through which the fluid runs into the pump-barrel. On the downward stroke, .the valve C closes, the valve G opens, and the fluid in the pump-barrel is forced through G, through the side-pipe or tube D, and into the main shaft A,at F. No power is needed on the downward stroke, the weight of the rods being suicient to carry the downward stroke',` and the weight of the ltherein of the-sand and sediment containe fluid in the shaft above the pump-barrel being neutralized by `its pressure on the piston both above and below. The side-pipe, D, is of suilicient length to prevent the scttlin in the fluid in the main pipe above the pumpbarrel, allowing the same to settle on'top of Q, the base of the lower member of the sandprotector and below the opening, F. The piston is adjusted in the pump-barrel so that the lowest point of its stroke is high enough above the opening E, and low enough below the opening F, to constantly retain the same fluid immediately above and below the piston and allow the sand and sediment con-A tainedin ythe incoming duid to pass around the pump-barrel and out at the mouth of the well. The lower member of the sand-protector is held in place on its beveled seat by the weight of the uid in the pipe above and by the springs, S. It is of suiicient length to permit the settling ot' sand or sediment on top of the base Q and below the bottom of the upper member P. The bottom of the upper member P is below the upper opening F of side-pipe D, to prevent. the' sand and sediment contained in the incoming fluid from entering'the pipe P. There is suiiicient .f space betweengthe piston-rod and themembers O and l", and between the members 0 and P, to permit the free passage of the fluid.v p y g Where the well ,produces gas with the mineral fluid, it is probable that the gas will collectv in the inverted pipe P, and orm angl() elastic cushion against which the upward stroke of the piston vwill work and thus lessen the amount of power required to carry the upward stroke of the piston.

With the pump described in this speciication, a large per cent of the lioating sand may be cleaned out of the well, dispensing` to a large extent with the use of the bailer. I claim asnew and desire to secure by Letters Patent:

l. A combination in'apump consisting of: Y a pump-barrel containing a solid piston; a piston-rod extending from the pump-barrel to the top of 'the well, to the bottom of which I the solid piston is attached; a sand-protector lcomposed of two members, through which opening into the lower part of he pump- 13o ber of the sandeprotector, with space be.-A

l 6. A combination n a pump consisting of: a -pump-barrel containing a solid piston composed oftwo series of reversed valvecups adjusted on the bottom of the pistonrod,- the upward series facing upward'and the lower series facing downward, its head in the lower valve-cup and lock-nuts screwed on the bottom of the piston-rod tight against the washer fitting into' the bottom valvecup; a piston-rod extending from the pumpbarrel to .the top of the well, to the bottom of which the solid piston is attached; a sidepipe or tube opening into the lower part of the pump-barrel below the lowest point of the downward strol-:e of the piston and into the main pipe above the -pump-barrel; a valve opening upward in the bottom of the pump-barrel; a perforated y,intakepipe below the pump-barrel; and a valve opening upward in the side-pipe or tube.
